Indianapolis Colts running back Marlon Mack has been ruled out of Sunday's game against the Jacksonville Jaguars after suffering a hand injury, per Zak Keefer of The Athletic.
The running back had been dominant before the injury, totaling 109 rushing yards and a touchdown on 14 carries to give Indianapolis an early lead.
Though he's been healthy this year, injuries were a significant problem for Mack in his first two seasons in the NFL.
The running back was limited with hamstring and foot problems throughout 2018 as well as a concussion, which held him to just 12 games.
